Cryptomate64 has a built-in ACOS5-64 Smart Card chip where all cryptographic operations, such as RSA (up to 4096bits), SHA-1, SHA-256, AES-128/192/256 and 3K 3DES, are performed, rather than in the PC or terminal. This ensures that all sensitive credentials protected by cryptographic keys cannot be hacked or sniffed - allowing ultimate security to be achieved.
